Hubbard and Heisenberg models on hyperbolic lattices: Metal-insulator transitions, global antiferromagnetism, and enhanced boundary fluctuations
Anika Götz, Gabriel Rein, João Carvalho Inácio +1
We study the Hubbard and Heisenberg models on hyperbolic lattices with open boundary conditions by means of mean-field approximations, spin-wave theory, and quantum Monte Carlo (QM…

Phases and Exotic Phase Transitions of a Two-Dimensional Su-Schrieffer-Heeger Model
Anika Götz, Martin Hohenadler, Fakher F. Assaad
We study a Su-Schrieffer-Heeger electron-phonon model on a square lattice by means of auxiliary-field quantum Monte Carlo simulations. The addition of a symmetry-allowed interactio…
